The Expo Pass is 49 €, we ask for zero personal data, and the whole ticket is a QR code in an email.

So it's transferable.

Buy one, give it to the friend who keeps almost getting it. Two days on the expo floor does more than four hours of you talking. 🧡

On a scale of 1 to 10, how worried are you about being a known Bitcoiner?

@RodolfoBits put that to the panel. @Jethroe111 answered by listing what he changed at home, then stopped short of naming the rest.
With @LyudaKozlovska and Nathan Day of @btcmap.

Two quantum milestones, one week.

26 Aug: @StarkWareLtd mined the first quantum-safe Bitcoin transaction on mainnet. No fork. Nonstandard, so it went via MARA Slipstream. Does nothing for keys already exposed.

27 Aug: Jonas Nick ( @n1ckler) published the SHRINCS BIP. 324 bytes against Schnorr's 64. Security proof still marked TODO.

Over 34% of all BTC has a public key on chain already.

Escape hatch or soft fork? 👇

nobody: absolutely nobody: me at 2am: let me just check my seed phrase is still where I left it. 🧡

Five years ago today, El Salvador became the first country in the world to make bitcoin legal tender. Someone tried it first. 🧡

Sparrow ( @SparrowWallet) 2.5.4 shipped after an AI-assisted code review. @craigraw says most of the fixes in the release came from it.

Coinkite believes AI may have helped whoever found the Coldcard seed generation flaw in July. That one rebuilt private keys without ever touching the device.

Same tool, both sides.

Net positive for self custody? 👇

Someone else can move your Bitcoin. @sethforprivacy of @cakewallet explains exactly who, and why more than 90% of Lightning users agreed to it without ever being told.

a block every ten minutes. through wars, elections, and every hot take on this timeline.

The BLAKE2b fork went live 1 Sept. SHA-256d out, so not a single existing ASIC can point at it.

No major exchange, wallet, custodian or Lightning implementation committed support.

One beta venue opened deposits. Bids $82, asks $190. A 130% spread on an empty book.

BIP-110 signalling peaked at 2.53%. It needed 55%.

When is a chain split just a research project? 👇

reply with your first Bitcoin purchase year. no amounts, just the year. ⚡

Luke Dashjr is out at OCEAN. Resigned as chairman, CTO and director on 29 Aug. Mummolin repurchased all his equity.

Stated reason: "different visions for the future of Bitcoin mining." Nothing more specific.

He is starting CONVOY. OCEAN's hashrate fell 96% in August.

What does this do to template diversity? 👇

We have not stopped since the last edition ended.
Long calls, full whiteboards, decisions already made.
None of it public yet. All of it real.
